78 students chose lion

3 0

Answer: 78 students

Step-by-step explanation:

Let the number of students who chose tiger be x.

The number of students who chose bulldog is 4 * x.

The number of students who chose lion is 2 * x.

7x = 273

x = 273/7 = 39

Your answer would be:

2 * x = 78.

hope this helps! :))

A restaurant earns $1445 on Friday and $1624 on Saturday. Write and solve an equation to find the amount xx (in dollars) the res
Gennadij [26K]
Total earned Friday = $1445
Total earned Saturday = $1624
Earnings Sunday - $xxx

Average over 3 day period = $1500
Therefor total over 3 day = $1500 x 3 = $4500
So earnigs friday + Saturday = $1445 + $1624 = $3069
                                                   $4500 - $3069 = $1431 earned on Sunday

How can you find the Mean Absolute Deviation (MAD) for this set of data?
den301095 [7]

Answer: Add all the absolute deviations and divide by number of swimmers.


Step-by-step explanation:

To find the mean absolute deviation of any data we need to follow the following steps:

  • Start by finding the mean of the data set.
  • Find the absolute value of the difference between each data value and the mean.
  • Find the sum of the absolute values of the differences.
  • Divide the sum of the absolute values of the differences by the number of data values.

We can see in the picture that it already dome with first two steps so the step after that is " Add all the absolute deviations and divide by number of swimmers."

2.386 rounded to the nearest tenth
svetoff [14.1K]

Answer:

Los números decimales son una combinación de números enteros y números que se encuentran entre los números enteros. A veces es importante poder comparar decimales para saber cuál es mayor. Por ejemplo, si alguien corrió los 100 metros planos en 10.57 segundos, y alguien más los corrió en 10.67 segundos, puedes comparar los decimales para determinar qué tiempo es más rápido. Saber cómo comparar decimales requiere el entendimiento del valor de posición decimal, y es similar a comprar números enteros.

 

Cuando trabajamos con decimales, hay veces que no se necesita un número preciso. En tal caso, es útil redondear números decimales. Por ejemplo, si la bomba de una gasolinera muestra que llenaste el tanque del carro de un amigo con 16.478 galones de gasolina, podrías querer redondear el número y decirle a tu amigo que le pusiste 16.5 galones.

Step-by-step explanation:

Otra forma de comparar decimales es comparar los dígitos en cada número, empezando con el lugar de posición mayor, que es el de la izquierda. Cuando un dígito en un número decimal es mayor que el dígito correspondiente en el otro número, entonces ése número decimal es mayor.

 

Por ejemplo, primero compara los dígitos de las décimas. Si son iguales, continúa con el lugar de las centésimas. Si esos dígitos no son iguales, el decimal con el dígito mayor es el número decimal mayor. Observa cómo se hace esto en los ejemplos siguientes.

Write the equation of a line that is parallel to 3x+2y=10 and passes through the point (4,-5). Answer in slope-intercept form.
SCORPION-xisa [38]

The equation of line is:

y = \frac{-3}{2}x+1

Further explanation:

The standard form of equation in point-slope form is:

y = mx+b

Given equation is:

3x+2y=10

We have to convert it into point slope form, for which we have to isolate y on one side of equation

3x+2y = 10\\2y = -3x +10\\y = \frac{-3}{2}x + \frac{10}{2}\\y = \frac{-3}{2}x + 5

Comparing with standard form:

m = -3/2

As the new line is parallel to given line, their slopes will be equal

So,

y = \frac{-3}{2}x+b

To find the value of b, putting the given point (4,-5) in equation

-5 = \frac{-3}{2}(4)+b\\-5 = -6+b\\b = -5+6 \\b = 1\\So\ the\ equation\ is:\\y = \frac{-3}{2}x+1
